We investigated the Systemic Lupus International Collaborative Clinics/American College of Rheumatology (SLICC/ACR) Damage Index as a predictor of severe outcome and an indicator of morbidity in different ethnic groups, and in regard to its validity. We retrospectively studied disease course within 10 yr of diagnosis in an inception cohort of 80 patients with systemic lupus erythematosus (SLE). The mean renal damage score (DS) at 1 yr after diagnosis was a significant predictor of endstage renal failure and the mean pulmonary DS at 1 yr significantly predicted death within 10 yr of diagnosis. Compared to Caucasians, Afro-Caribbeans and Asians had significantly higher mean total DS at 5 and 10 yr, and higher mean renal DS at 10 yr. At 5 yr, the mean renal DS in Afro-Caribbeans and the mean neuropsychiatric DS in Asians were significantly higher than in Caucasians. The rate of endstage renal failure in Caucasians was significantly lower than in the other ethnic groups. Our results confirm the validity of the SLICC/ACR Damage Index.

To evaluate the results, the long-term prognosis and the rates of complication of an immunosuppressive regimen with corticosteroids and cyclophosphamide in the treatment of the nephritis of systemic lupus erythematosus, 21 patients with lupus glomerulonephritis were studied. Renal biopsies were performed in 17/21 of them and indicated diffuse proliferative (6 patients), diffuse mesangial (4) and membranous (7) glomerulonephritis. Treatment was structured in 4 phases: 1) induction with methylprednisolone 250 mg i.v. for 7-14 days, and cyclophosphamide 100-200 mg p.o., q.d., or 20 mg/kg i.v. every 28 days; 2) maintenance with prednisone p.o., 2 mg/kg q.o.d. for 45 days, and cyclophosphamide as before; 3) tapering, with reduction of prednisone by 15% each month for 4 months; 4) indefinite maintenance with prednisone slowly tapered to the least effective q.o.d. dose and cyclophosphamide discontinued after six months of treatment. This cycle was repeated in the event of a relapse. After a first immunosuppressive cycle, 20/21 patients achieved remission of glomerulonephritis. Plasma creatinine fell from 97 +/- 6 to 80 +/- 3 microMol/l (p < 0.01). Proteinuria fell from 2.1 +/- 0.4 to 0.2 +/- 0.4 g/d (p < 0.0001) and the nephrotic syndrome, present in 8 patients, disappeared. After an average of 20 +/- 7 months, 8 patients relapsed: all remitted again after a repeat cycle, but 1 later progressed to end-stage renal failure during pregnancy. After an average of 56 months 4 out of these 8 patients relapsed again: 1 progressed to end-stage renal disease following an abortion and 3 remitted completely after a third cycle. Thus, 18 out of 21 patients are presently in remission with an average dose of prednisone of 13.7 mg/day after an average follow-up of 52 +/- 38 months (range 2 to 156). Three patients are presently off treatment. In 16 patients with extended follow-up of 2 to 13 years, anti-nuclear antibodies, anti-DNA antibodies, albuminuria and cylindruria fell below post-cycle levels (p < 0.001 for all). We conclude that intensive immunosuppression with steroids and cyclophosphamide can achieve excellent long-term results in the treatment of systemic lupus with glomerulonephritis.

Immunosuppressor and immunomodulator therapies are widely used for the treatment of patients with severe systemic lupus erythematosus. In case of certain organ involvement (kidney, brain, heart), corticosteroids should be associated with immunosuppressors, especially cyclophosphamide. Cyclophosphamide, a powerful immunosuppressor, is generally given in an intravenous bolus rather than orally. Aziathioprine is proposed after cyclophosphamide or in less forms at onset. The therapeutic strategy in severe forms may require plasma exchange, carefully synchronized with the cyclophosphamide bolus. Depleted antibodies following plasma exchange induces a stimulation of B clones which produce antibodies sensitive to cyclophosphamide. Other immunomodulator treatments have also been used, for example cyclosporine or intravenous immunoglobulins. Cyclosporine has not been shown to be effective in severe lupus. Inversely, in certain conditions, cyclosporine can be used to limit other treatments although it does not have a significant effect on autoantibody levels. Intravenous immunoglobulins have been used at high dosages but only in selected cases due to undesirable side effects. Certain cases of renal failure induced by immunoglobulins have been described. Immunosuppressor or immunomodulator therapy is often required in systemic lupus erythematosus. Treatment modalities must however be carefully established in order to limit the predictable side effects while achieving maximal efficacy.

The aim of the study was to determine the correlation between some clinical parameters and histopathologic findings in patients with lupus nephropathy. Eighteen patients (17 female and one male) with the diagnosis of lupus nephritis were examined at the Nephrological Clinical of the Faculty of Medicine. Three to eight months passed between diagnosing systemic lupus erithematosus and kidney biopsy. At the time of biopsy the average age of patients was 33.3 +/- 2.9 years (18-52 years). In more than half of the 18 cases the disease was evidenced as nephrotic syndrome, but most of them had renal failure and increased blood pressure. In patients with diffuse proliferative glomerulonephritis proteinuria was significantly higher than in other histopathologic groups. Serum nitrogen was considerably higher while creatinine clearance was much lower in patients with diffuse proliferative glomerulonephritis than in other histopathologic groups. Circulating immune complexes were increased, and the complement (C3 and C4) concentration was slower in patients with lupus nephropathy, but the significant difference was present only when diffuse glomerulonephritis was compared to other histopathologic groups.

Lupus nephritis is a prototype of immune complex-mediated glomerulonephritis. A broad range of clinical presentations and histological changes (proliferative, membranous, or both) are observed. Patients are at risk for progressive renal function deterioration as a result of the interaction of various active immunologic and chronic sclerosing mechanisms of kidney injury. Hypertension and hyperlipidemia contribute to morbidity and mortality. Monitoring serological parameters, urinary protein excretion rate and, especially, the urinary sediment facilitate the prompt recognition and treatment of this disorder. Kidney biopsy evaluation often clarifies the type, severity, and potential reversibility of the underlying renal lesions. Although contemporary immunosuppressive regimens for proliferative lupus nephritis have reduced the risk of end-stage renal failure, they are potentially toxic and not universally effective. Decisions regarding the intensity and duration of these treatments are difficult and are based on the severity of the disease, the initial response to therapy, and the risk for drug-induced toxicities. Studies are in progress to evaluate alternative regimens for proliferative lupus nephritis and membranous lupus nephropathy.

The factors that determine a patient's susceptibility to specific target organ involvement in systemic lupus erythematosus (SLE) remain unknown. Lupus nephritis can be a particularly devastating complication, with an increased mortality and the risk of progressive renal damage resulting in end-stage renal disease (ESRD). This analysis was performed to determine whether renal disease aggregated in select families or was a sporadic complication in patients with SLE. We compared the family history of ESRD in 50 patients with SLE complicated by lupus nephritis with 37 controls who had SLE but lacked nephritis after a mean follow-up duration of more than 11 years. The frequency of relatives with ESRD in the lupus nephritis cases was compared with that in controls using Fisher's exact test (significance at P < or = 0.05). Fifty percent (25) of the 50 lupus nephritis patients were black and 50% (25) white, in contrast to 35% (13) and 65% (24) of the 37 lupus non-nephropathy controls, respectively. A first-, second-, or third-degree relative with ESRD was present in 16% (eight) of the 50 lupus nephritis cases and in 0% of the 37 SLE non-nephropathy controls (P = 0.019, Fisher's exact test, two-tail). Twenty-eight percent (seven) of the 25 black patients with lupus nephritis had relatives with ESRD compared with 0% of the 13 black lupus non-nephritis controls (P = 0.07). Only one of the eight relatives with ESRD had SLE or a collagen vascular disease. Lupus nephritis patients and the non-nephritis controls had similar ages (mean +/- SD: 38.5 +/- 10.0 years v 46.6 +/- 11.8 years; P = 0.28), family sizes (6.27 +/- 2.61 first-degree relatives v 6.35 +/- 3.25 first-degree relatives; P = 0.16), and duration of SLE (9.26 +/- 5.94 years v 11.35 +/- 6.43 years; P = 0.60). Familial clustering of ESRD was observed in black patients with SLE who had nephritis. This was unlikely to be related to differences in patient age, family size, or duration of SLE. This data, coupled with the known familial aggregation of ESRD in blacks with hypertensive and diabetic ESRD, supports the contention that genetic factors contribute to the familial clustering. The presence of relatives with etiologies of ESRD other than SLE suggests that there is an inherited susceptibility to progressive renal failure, independent of the etiology of ESRD.

We report the response to risperidone in seven hospitalized, adult patients who presented psychotic symptoms etiologically related to a general medical condition. The conditions included brain surgery in two, and anticardiolipin syndrome, renal failure, epilepsy, lupus, and metastatic carcinoma in one each. Four patients had failed previous treatment with at least one typical antipsychotic agent. Response to risperidone was assessed by the Brief Psychiatric Rating Scale (BPRS). Serum was collected for measurement of steady-state trough risperidone and 9-hydroxyrisperidone concentrations at effective doses in three patients. Amelioration of psychotic symptoms was noted in all seven patients. Mean (+/- SD) BPRS scores were reduced significantly from baseline (63.0 +/- 15.1) to endpoint (27.0 +/- 3.5; p < 0.01). The mean effective daily dose of risperidone was 3.1 +/- .7 mg and time to response was 4.7 +/- 2.4 days. Risperidone was not present at detectable concentrations in the three patients studied. The mean steady-state trough serum concentration of 9-hydroxyrisperidone in the three patients assessed was 20.3 +/- 9.8 ng/ml. These preliminary findings, which suggest that risperidone is a safe and effective agent in patients with psychotic symptoms due to various medical conditions, need to be confirmed by randomized, antipsychotic comparison trials involving a larger number of patients.

Colitis in systemic lupus erythematosus (SLE) poses a diagnostic challenge as clinical, radiological and laboratory findings are often non-specific. Fulminant amoebic colitis is a rare cause of death in SLE. Early diagnosis coupled with timely surgery can reduce the mortality. The demonstration of haematophagous trophozoites in the stool is diagnostic but insensitive. Early endoscopy with adequate specimen collection is an important part of the diagnosis. Serology is both sensitive and specific but can take up to 2-4 weeks for seroconversion making it less useful in a disease that takes a rapid downhill course if treated inappropriately. We report a fatal case of colitis in a patient with SLE due to invasive amoebiasis which was complicated by Salmonella bacteraemia, disseminated intravascular coagulation, acute oliguric renal failure and adult respiratory syndrome. We also reviewed the literature on the clinical features and diagnosis of fulminant amoebic colitis. Amoebic colitis, although rare, should be considered in the differential diagnosis of lupus patients with colitis.

In this report, the outcome, diagnosis, management, and complications of pregnancy in dialysis patients are discussed. The advantages and disadvantages to the use of peritoneal dialysis and hemodialysis and the changes in dialysis regimen used in pregnant women are addressed. Maternal complications, particularly hypertension and anemia, are reviewed. This report looks at the approach to the management of anemia and calcium/phosphorus metabolism in the setting of limited information. The report also discusses pregnancy outcome for the mother and fetus, including the problem of prematurity and fetal loss. Special considerations in women with lupus and diabetes are noted. Pregnancy in dialysis patients remains a high-risk undertaking for both the patient and the infant. There are large gaps in our knowledge base regarding the effect of the abnormalities associated with renal failure on pregnancy. The survival of the infant and the safety of the mother depend on close cooperation among all the specialities involved, including nurses, doctors, nutritionists, and social workers from nephrology, perinatology, and neonatology.

A 22 year-old woman with a seven year history of (SLE) was readmitted because of oliguria, edema, dyspnea and arterial hypertension. She had a previous biopsy diagnosis of focal glomerulonephritis, (WHO III b), and had been treated with immunosuppressors and steroids. Laboratory data showed lupus activity, AHM with thrombocytopenia, nephrotic-range proteinuria and renal failure. A second renal biopsy was performed showing diffuse proliferative nephritis, (WHO IV), in association with noninflammatory necrotizing vasculopathy with luminal obliteration. She started with hemodialysis and was subsequently treated with methylprednisolone pulses, plasmapheresis, cyclophosphamide and oral steroids. During the inpatient period, she had generalized seizures, acute lung injury and pulmonary hemorrhage. These complications, the AHM and the thrombocytopenia receded totally. Renal function was never resumed. We emphasize that this association of diffuse proliferative nephritis with noninflammatory necrotizing vasculopathy is not infrequent and has a poor renal prognosis. The AHM with thrombocytopenia was interpreted as secondary to endothelial cell damage due to vasculopathy.
